I tested your link with a character that can "read" websites to see how big the text actually is.
The highlighted part basically says "This is way too much text, I'll ignore what is over the maximum I can handle."
Since all of perchance uses the same model for AI text things, a generator with the sole purpose of creating lore out of something like that will face the same problem - you'd need to use a major company LLM for that with a higher token limit.
This is ALL of the text on this site (~21,600 characters), just the synopsis text would be fine, that's not even 7,000 characters.
I fed that synopsis to Loreena, a character created by Petra to create Lore entries, this is the result:

Maybe this is close enough to what you are seeking. If not, you can try the same with Gemini or other major company LLM for probably better results.

There are NO working video generators on perchance. Perchance does NOT provide video generation services. You can NOT create videos using perchance.
You can ONLY generate images from prompts, nothing else - and chat with the AI.
Any generator claiming otherwise is wishful thinking, fake or worse (there are very few ones that "borrow" resources from outside of perchance and make it seem like perchance can do, which adds to the confusion.)
In your case, you can take a look at the code (edit button top right corner) and see this piece of "code".
